The Solvability Conditions with Hermite Part Positive Semidefinite and Hermite Positive Semidefinite Solutions of the Matrix Equation (A*XA, B*XB)=(C, D)
The complex matrix solutions with Hermite part positive semidefinite and Hermite positive semidefinite for the matrix equation (A*XA, B*XB)=(C, D) is investigated. The necessary and sufficient conditions for the solvability of such solutions are derived by using the generalized singular value decomposition. The forms of general solution are also given out.
